Stellaris^® LM3S601 Microcontroller
1 Architectural Overview
The Stellaris^® family of microcontrollers—the first ARM® Cortex™-M3 based controllers—brings
high-performance 32-bit computing to cost-sensitive embedded microcontroller applications. These
pioneering parts deliver customers 32-bit performance at a cost equivalent to legacy 8- and 16-bit
devices, all in a package with a small footprint.
The LM3S601 microcontroller is targeted for industrial applications, including test and measurement
equipment, factory automation, HVAC and building control, motion control, medical instrumentation,
fire and security, and power/energy.
In addition, the LM3S601 microcontroller offers the advantages of ARM's widely available
development tools, System-on-Chip (SoC) infrastructure IP applications, and a large user community.
Additionally, the microcontroller uses ARM's Thumb®-compatible Thumb-2 instruction set to reduce
memory requirements and, thereby, cost. Finally, the LM3S601 microcontroller is code-compatible
to all members of the extensive Stellaris family; providing flexibility to fit our customers' precise
needs.
Texas Instruments offers a complete solution to get to market quickly, with evaluation and
development boards, white papers and application notes, an easy-to-use peripheral driver library,
and a strong support, sales, and distributor network. See “Ordering and Contact
Information” on page 561 for ordering information for Stellaris family devices.
